Flexibility in general is the main reason I'd use an AP that can be turned into a Workgroup Bridge like the WET11. The WET11 would certainly work and if all that he ever needed that device to do was bridge to an AP it would work well. 80 mW I believe, which is nice, and SMA connectors for a directional antenna if required, which at 1500 feet it would be. An advantage the WET11 appears to have over it's AP cousins with a "client mode", is that it apparantly will associate to any 802.11b AP, where as the client mode AP's, from what I have read anyway, are a bit more finicky.
